Hiboom Swimming Pool Diving Balls – Underwater Water-Filled Balls for Teens & Adults (9-Inch, Multi-Color)
Hiboom Swimming Pool Diving Balls – Underwater Water-Filled Balls for Teens & Adults (9-Inch, Multi-Color)
The Hiboom Swimming Pool Diving Balls are water-fillable PVC balls designed for underwater passing, dribbling, and diving games. Each ball inflates to about 9 inches and comes with a hose adapter and filling needle for easy water and air adjustment. The multi-color design features rainbow, watercolor, and fruit patterns that resist fading. These balls are suited for teens, adults, and older kids who want active pool play.
How do these diving balls work underwater?
You control the buoyancy by adjusting the water-to-air ratio inside the ball. Fill mostly water and a little air to make it neutrally buoyant—it will sink slowly and float just below the surface. This lets you pass, dribble, and dive for the ball, combining elements of pool football and water basketball. The thicker PVC material can handle rough play and underwater impact without cracking.
What's included and how to set them up
- One multi-color pattern diving ball (random design from rainbow, watercolor, or fruit themes)
- Compatible hose adapter (fits standard 1/2-inch or 5/8-inch garden hoses)
- Filling needle for air inflation
- Fill with water and some air through the hose adapter; remove needle after filling. Clean with warm soapy water and dry after use.

The hand-sized balls work well for teens and adults looking for active underwater games. They’re also a good choice for older kids who can hold their breath and dive. The game rule suggested by the brand: the team that lets the ball break the surface loses.
Frequently asked questions
Do I need to inflate them with just air? No, they need both water and air. Fill with water first, then add air using the included needle to get the desired buoyancy.
Are the colors safe for pool water? The PVC material is described as safe for family use, and the printed patterns are made to resist fading from chlorinated or saltwater pools.
Is a pump included? No pump is included, but you can use any standard air pump with a needle tip (most bike or sports ball pumps work).
Can these be used in lakes or ponds? Yes, the product mentions use in pools, lakes, and ponds. Just be mindful of sharp objects that could puncture the ball.
